The aim of this study was to evaluate the effect of ergonomic workstation design on musculoskeletal risk factors (MRFs) and
musculoskeletal symptoms (MSSs) reduction among female semiconductor fabrication room (fab) worker. A prospective study was
conducted to follow up 40 female fab workers over 3 months after intervention. The intervention program focused on reducing shoulder
loadings for 20 female fab workers by redesigning nine workstations. Simultaneous comparisons were made for the other 20 female fab
workers using original workstations. One customized observation checklist and Nordic musculoskeletal questionnaire were used to
evaluate workers’ MRFs and MSSs, respectively. One month after intervention, MRFs of awkward shoulder postures and repetitive
motions and MSSs in shoulders for the intervention group were significantly lower than those for the control group. The lowering effects
persisted for 3 months on awkward shoulder postures but lasted for only 1 month on repetitive motions and shoulder symptoms after
intervention.
